Tiif: weatlier during tlie quarter was very remarkable for continued 
low temperature, frequent rain, large amount of cloud, little suu- 
.shine, and bad weather generally. The temperature within the 
three months reached its average on 9 days only, and fell short on 
83 days ; the mean excess on the 9 days was less than 1° ; whilst 
the average daily deficiency for the 83 days exceeded 4°. The mean 
temperature of July was 4°'3, in August 3°"8, and in September S*^"?, 
in defect, as compared with their respective averages from the pre- 
ceding 19 years. As compared with the year 1859, July was 10°*o, 
August 5^-8, and September 3''"3 colder. The mean temperature of 
the three months ending September was 5G°'2, and once only, viz., 
in 1817, has the mean temperature of the same months been so low 
since the year 1771. The mean temperature of the four months 
ending September is still more remarkable ; its value was 55^*9, and 
there is no other instance, as far as trustworthy records extend, of 
a temperature of so low a value for these four important months. 
The mean pressure of the atmospheie in July was a little above, 
in August much below, and in September below their respective 
averages. The pressure in August was less than in any August in 
the preceding 20 years. The jn-essure was less in August than in 
July at extreme southern stations by 0-25 in., increasing gradually' 
to 0*40 in. at northern stations. It was greater in September than 
in August by O'lo in. at southern stations, gradually increasing to 
■0"33 in. at extreme northern stations. 
The temperature of the dew-point was below its average in JiUy 
and August to the amount of 1°-G, and in September to 0 -09. 
The fall of rain in July was 2-8 in., in August 3*7 in., and in Sep- 
tember 3-1 in. ; amounting in the three months, to 9'G in., and being 
2-1 in. in excess. The fall of rain from January 1 is 2o-l in., being 
G*9 in. in excess. 
The mean temperature of the air at GreenAvich for the thi-ee 
-months ending August, constituting the three summer months, was 
:56-*7, being 3^-4 below the aA-erage of the preceding 89 years.
